In this paper different approaches to investigate the behaviour of tunnel under seismic loads are presented. They include one-dimensional (1D) numerical analyses performed modelling the soil as a single phase non-linear visco-elastic medium, the results of which are then used to evaluate the input data for selected analytical solutions proposed in the literature (uncoupled approach), and 2D fully coupled Finite Element (FEM) simulations adopting a visco-elastic effective stress model for the soil (coupled approach).
